I'm also agree with Sarmad, According to the ASIWG meetings we tried to 
discover the correct context of each characters within the Arabic 
Script. As we should keep the exception list very small, it would be 
better to re consider the characters which miss classified and find out 
a rule in order to get more accurate classification. Patrik, would it be 
possible for you to summarize the classification procedure you run on 
the Unicode table to classify the characters ?

Best Regards,
